Hello,

It depends on whether you trust the data (if it's yours and you *know*
they're IP addresses) and just want to automate, or not..

>>> pattern = re.compile(r'\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}')

Tested on:

>>> test = "ip=192.168.1.36 port=4992 ip=255.255.255.255 port=80"

Gives:

['192.168.1.36', '255.255.255.255']


Add "ip=" in order to avoid confusion (data may have by chance something
that looks like an IP address, but the "ip=" bit acts as a discriminant.

>>> pattern = re.compile(r'ip=\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}')

Testing for the string test:

test = "ip=192.168.1.36 port=4992fdjsqklmfqsjdkip=192.168.541.36
port=222 2.2.2.2random"


Gives:

['ip=192.168.1.36', 'ip=192.168.541.36']

It ignores the 2.2.2.2 because it doesn't have "ip=" in front of it, and
was just lucky to have an IP address structure.

You can then split "ip=" out of each item to have the IP address.
